We report our calculation of the heavy-light decay constants fB and fD on a 203 x 48 lattice at 0 = 5.2 with nf = 2 sea quarks by the fully O(a)-improved Wilson fermion and heavy quarks in Fermilab formalism. We find that the B meson decay constants are consistent with those obtained with the NRQCD
